title: Early versus Late Surgical Treatment for Neurogenic Thoracic Outlet Syndrome.
abstract: Objectives. To compare the outcome of early surgical intervention versus late surgical treatment in cases of neurogenic thoracic outlet syndrome (NTOS). Design. Prospective study. Settings. Secondary care (Al-Minia University Hospital, Egypt) from 2007 to 2010. Participants. Thirty-five patients of NTOS (25 women and 10 men, aged 20-52 years), were classified into 2 groups. First group (20 patients) was operated within 3 months of the onset and the second group (15 patients) was operated 6 months after physiotherapy. Interventions. All patients were operated via supraclavicular surgical approach. Outcomes Measures. Both groups were evaluated clinically and, neurophysiologically and answered the disabilities of the arm, shoulder, and hand (DASH) questionnaire preoperatively and 6 months after the surgery. Results. Paraesthesia, pain, and sensory nerve action potential (SNAP) of ulnar nerve were significantly improved in group one. Muscle weakness and denervation in electromyography EMG were less frequent in group one. The postoperative DASH score improved in both groups but it was less significant in group two (P < .001 in group 1 and P < .05 in group 2). Conclusions. Surgical treatment of NTOS improves functional disability and stop degeneration of the nerves. Early surgical treatment decreases the occurrence of muscle wasting and denervation of nerves compared to late surgery.
